A measuring probe, able to access data flows composed of packets transmitted along a path formed by a plurality of equipment in a telecommunication network, having a measurement module to perform measurements in accordance with the configuration data, a determination module for determining that one or more transmitted packets form a signaling message, and a signaling module to determine configuration data from the signaling message.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A measuring probe, comprising: means for accessing data flows composed of packets, transmitted along a path formed by a multiplicity of equipment in a telecommunication network; measurement means for performing measurements, in accordance with configuration data; determination means for determining that one or more packets transmitted along the said path form a signaling message; and signaling means for determining said configuration data from said signaling message wherein said measurement means are operable to transmit measurement reports, containing said measurements, to a measuring device determined by an identifier contained in said configuration data; and said measurements are transmitted to said measuring device by means of a proxy, the measurement reports transmitted to said proxy containing said identifier.
2. The measuring probe in accordance with claim 1 , wherein said measurements are relative to said data flow.
3. The measuring probe in accordance with claim 1 , wherein said determination means are operable to read a specific label, contained in said received message, and determine whether the said received message is a signaling message from this specific label.
4. The measuring probe in accordance with claim 1 , wherein said configuration base contains a set of records, each record corresponding to a measurement task and each record comprising: a filter which determines the packets on which the measurements must be performed; and parameters relating to the method of measurement.
5. The measuring probe in accordance with claim 4 , in which said parameters are chosen from the group of factors comprising: the time during which the measurements must be performed; sampling data a hashing function; a parameter triggering a time-stamping of the packets to be measured; a parameter triggering an identification of the packets to be measured, by means of a hashing function; a parameter triggering a counting of the packets to be measured; a method for transmitting the measurements to the measuring device (M).
6. The measuring probe in accordance with claim 1 , wherein the transmissions with the measuring device are made secure.
7. The measuring probe in accordance with claim 6 , wherein means for making the transmissions with the measuring device secure are transmitted by a signaling message.
8. The measuring probe in accordance with claim 1 , further comprising: means for deciding whether said signaling means creates a new measurement task, in accordance with a sensitivity indicator associated with said measuring probe.
9. The measuring probe in accordance with claim 8 , wherein said means for deciding also decides as a function of a priority contained in the said received message.
10. A router comprising the measuring probe in accordance with claim 1 .
11. The telecommunication network comprising measuring probes in accordance with claim 1 .
12. The telecommunication network in accordance with claim 11 , further comprising measuring devices.
13. A method for taking measurements of data flows composed of packets, transmitted along a path formed by a multiplicity of equipment in a telecommunication network, the method comprising: performing measurements, in accordance with configuration data; determining that one or more packets transmitted along the said path form a signaling message; determining said configuration data from said signaling message; transmitting measurement reports, containing said measurements, to a measuring device determined by an identifier contained in said configuration data; and transmitting said measurements to said measuring device by means of a proxy, the measurement reports transmitted to said proxy containing said identifier.
14. The method of claim 13 , wherein said measurements are relative to said data flow.
15. The method of claim 13 , wherein said determining comprises reading a specific label, contained in said received message, and determining whether said received message is a signaling message from this specific label.
16. The method of claim 13 , wherein said configuration base contains a set of records, each record corresponding to a measurement task and each record comprising: a filter which determines the packets on which the measurements must be performed; and parameters relating to the method of measurement.
17. The method of claim 16 , in which said parameters are chosen from the group of factors comprising: the time during which the measurements must be performed; sampling data a hashing function; a parameter triggering a time-stamping of the packets to be measured; a parameter triggering an identification of the packets to be measured, by means of a hashing function; a parameter triggering a counting of the packets to be measured; a method for transmitting the measurements to the measuring device (M).
18. The method of claim 13 , wherein the transmissions with the measuring device are made secure.
19. The method of claim 18 , wherein means for making the transmissions with the measuring device secure are transmitted by a signaling message.
20. The method of claim 13 , further comprising: deciding whether a new measurement task is created, in accordance with a sensitivity indicator associated with said measuring probe.
21. The method of claim 20 , wherein said deciding is decided as a function of a priority contained in said received message.
22. A router comprising a measuring probe implementing the method of claim 13 .
23. A measuring probe, comprising: means for accessing data flows composed of packets, transmitted along a path formed by a multiplicity of equipment in a telecommunication network, said data flows passing through said measuring probe; measurement means for performing measurements, in accordance with configuration data; determination means for determining that one or more packets transmitted along the said path form a signaling message; and signaling means for determining said configuration data from said signaling message; wherein said determining comprises reading a specific label, contained in said one or more packets, and determining whether said one or more packets are a signaling message from this specific label.
24. The measuring probe of claim 23 , wherein said signaling message triggers an establishment of a new measurement task.
25. The measuring probe of claim 23 , wherein said signaling message triggers a modification of a measurement task.
26. The measuring probe of claim 23 , wherein said signaling message triggers a deletion of a measurement task.
27. The measuring probe of claim 23 , wherein said signaling message comprises two or more packets.
